Blessed

A curses-like library for Node.js. Mature but unmaintained since 2017.

Language: JavaScriptRuntime: Node.jsWebsiteSource

Blessed was the original Node.js TUI library, providing a curses-like API with a rich widget set (lists, forms, tables, logs). Written in pure JavaScript with no native dependencies.

Blessed targets the Core TUI baseline — it works with basic terminal features and predates most modern protocols. The library has been unmaintained since 2017 but still sees usage in legacy projects. For new projects, consider Ink (React-based) or Silvery (React + modern protocols).
